Frequently Asked Questions


What’s the most common disease problem on Fragaria × ananassa (Sweet Charlie), and how do I control it?
A common issue is gray mold (Botrytis) on ripe fruit, especially when nights are cool and humidity stays high. Remove and discard any rotting berries, improve airflow by keeping plants unmulched away from the crown, and water in the morning so foliage dries quickly. If gray mold keeps recurring, use a preventive program with a label-approved fungicide for strawberries and avoid overhead watering.
How often should I water Sweet Charlie during peak growth, and what soil moisture target should I maintain?
During flowering and fruiting (about the main 6–8 weeks before the 90-day mark), keep the soil consistently moist but not waterlogged—aim for the top 1 inch to feel evenly damp. Water deeply 1–2 times per week depending on heat and rainfall, then reduce frequency once berries start to ripen to prevent diluted flavor and rot. If the soil dries out between waterings, berries can be small and uneven.
How can I tell when Sweet Charlie strawberries are ready to harvest?
Harvest when berries are fully red from the top to the tip and the seeds at the surface look slightly raised and dry—not white or pink at the center. Pick every 1–3 days during the ripening window, because Fragaria × ananassa continues producing and berries can over-soften quickly. For best flavor, pick in the morning after dew has dried and before the plants get hot.

Sweet Charlie bursts with a vivid, glossy scarlet sheen and a fragrant, sun-warmed sweetness that feels like summer on the tongue. The berries are medium to large with a classic conical shape, firm yet tender-fleshed, and richly juicy—ideal for savoring at peak ripeness. Grow Sweet Charlie for abundant garden harvests and for making your preserves shine with its bright berry character.

Sowing Tips

Transplant Conditions

Wait until soil reaches 50°F and nights stay above 40°F before moving outdoors.

Expert Note

Plant crowns at soil level (not buried), keep mulch on once established, and water consistently the first season to lock in strong runners and next year’s yield.
